“Yeah but what about brain density or ratios of grey to white matter?” Yeah. Those do vary. You wanna know how much they vary? So much that scientists cannot reliably determine sex from brain scans. They could determine sex by looking at the chromosomes inside a neuron, but they cannot reliably predict sex because the variation is so immense and the differences so subtle. Think of it like height - you might be able to guess that a 4’1 ft adult is female and a 6’8 ft adult is male, but can you guess the sex of someone who is 5’6ft? Probably not.
So, if scientists can’t tell normal men apart from normal women using brain scans… how the fuck are they going to determine which males have “lady brains”? It’s actually difficult for me to articulate how fucking retarded this is. It’s a category error. You went into this assuming that trannies were telling the truth when they said they had ladybrains, and never considered whether women themselves even had ladybrains.
